Ford F-150 - 1997-2003 :: V8 Just Stops Without Stalling
Apr 26, 2015
I have a 2003 f150 2WD crew cab with a 4.6 V8 engine it has 178,000 miles on it. The other day after I started it to leave work it died on me without hesitation almost like the ignition switch was turned off I tried to restart and it would turn over but wouldn't start so I switched the ignition all the way off and it started right up, going down the road it did it again.
If I try to restart without turning the ignition all the way off it won't start but if I turn it all the way off it will start up first try, it has done it a couple times since and its the same way every time, where to start. My check engine light has been on for some time for something else so I don't know if it picked up a code or not I don't have a code reader to see if it has a new code...

My 2003 ranger xlt 4.0 has a stalling problem. The engine light came on in aug and I had it coded at AutoZ and there was a code for the oxy sensor, changed that and didn't work so I took it back. In oct I had it coded and it said the air int temp sensor which i was informed was part of the mas airflow sensor, changed that the beginning of nov, got the computer to reset and it still didn't fix it.
Took that part back and had it coded again a few days later and several codes came up AutoZ code 1732 and the the OEM number to cross for them were: P2195 , P0300 , P0316 , P0174 , P0171 , P2197 . Reset the comp yesterday and as soon as the light came on had them code it again and it came up AutoZ code 1732 OEM # to cross P2195. I guess my next step will be to take it to the dealers to get diagnosed..

My speedometer was intermittent for a while, stalling, then moving, but never above the actual speed. Now I turn it on, but as soon as I move, it travels up to 38mph then stays there until I turn off the engine, then it hangs for 4/5 seconds, then drops to zero.
I replaced the VSS in the rear diff, and the one on the tranny. I checked all fuses. There are no other dummy lights or indications. Bad ground? I'm hoping I don't need a new gauge cluster.

2001 F150 5.4 v8 ... In the past few months my truck has been a bit strange, but in the past few weeks it's gotten to the point I'm nervous to drive it. Usually when shifting around 30-35, the engine revs up and stops accelerating and I have to take my foot off the pedal to make it return to normal. It doesn't do this after I do that, but the past time I tried to drive I couldn't get above 35 and the rpm was in the upper 2000s going at a constant 35. When I stop for any reason such as making a turn, when it shifts it lurches forward and I hear a loud clunk.
Naturally, I've checked all the fluids and fuses and they're all fine. The mechanic I regularly visit insists that nothing is wrong with it.

On my 01' the bottoms of the bump stops are completely gone. Rusted out to the point to where the rubber stop on the front lower control arm (if the truck bottomed-out) would go right thought it. The rubber stops are fine.
This pic was taken from below the control arm looking up. You see the rubber bumper and just above it is the stop (some what triangular shaped). the bottom is rotted away... Are these replaceable or repairable? They seem like they are welded to the frame.

I've recently had problems with my truck running 97 f150 4.2L.The latest episode is it stalling when coming to a stop. It will start right back up, I've checked for codes and found none, I have changed the fuel and air filters and I have tested the fuel pressure.(I have a video of the test however I don't know how to upload it.) Key on engine off it pumps up to 30 immediately on the gauge. key on engine running gauge shows a steady 32. I am really at a loss for what to check next. I really need this truck dependable again ASAP my wife is scared to drive it.

my 97 f150 4.2L keeps stalling on acceleration. It ran fine this morning then my wife put 20 dollars of fuel in it and drove 30 miles to her destination with no problem. on her way back the truck started bucking bogging down and acting like there was a fuel problem but it didn't kill. I checked for codes there were none. I removed the fuel filter on the rail and replaced it with a new one. Now it will idle fine with no miss but if I give it gas it kills.
I checked the codes again there are none. I also checked to make sure there was fuel coming from the tank when I turned the key as well as making sure I heard the fuel pump kick on when I first turned the key.I am leaning towards water in the fuel,i didn't see any trash come out of the old filter, however I am not sure. I have a 175 mile commute to and from work.

I have a 2003, 4.6 F-150 with 201,500 miles
I am having some A/C issues. It's just too hot out there.
#1 The truck has a lack of power when I have the A/C on. It feels like it wants to stall out in the lower RPM's. I loose power when I go 65mph+. The truck actually stalled on me yesterday in the parking lot. I turned off the A/C and it ran fine.
#2 I have to go over a 5000ft pass daily, I turn off the A/C when I go over it. Below the pass, the A/C doesn't work well and it's not as cold. But when I get over the pass, the A/C turns very cold. The pass is like a 3-4 mile stretch.

Ford F150 truck, when starting, the starter will turn over strongly for half a second then just abruptly makes a loud noise and stops. It won't ever fully crank. Is this just a bad starter?

2002 f150 7700 with 5.4 triton and 4r100 tranny started chugging under acceleration and now stalls when put in D, 2 or 1. park and neutral are fine and reverse works perfectly.
Now when I put it in drive it chugs and stalls immediately... 1/10 times it will keep running but chug violently like its running out of gas. will get worse and stall if you press the gas. i can light the tires up for a block in reverse however.
Changed coils 1 2 and 3, IAC, bank 1 knock sensor, camshaft position sensor

I recently got a 2wd 1994 150 straight 6 4.9L, It's been a great truck so far. It drove from New Mexico to California with no issues. Just this morning it started stalling and dying when pulling up to stop lights and putting it in reverse. The truck has 172,000 miles and has a new serp belt, alternator, radiator, and starter. It seems to run just fine on the highway and once it's warmed up it doesn't stall as easily. There is an exaust leak.

I have a 2001 Ford Escort with 92,000 miles that recently has started stalling when coming to stops. It's especially bad on stop and go traffic. It starts up easily every time, and once I'm actually driving with steady speeds, it has no problems. I've had plans to go out of town this Memorial weekend and visiting friends about 200 miles away (400 round trip). The earliest that I can get the car into the mechanic is Tuesday. This trip would be mostly highways and very few stops, but I don't know if it's safe to do so. Would I potentially be causing damage to the engine?

I have got the most aggravating electrical gremlin possible. For over a year now, the truck intermittently just dies. Mostly it happens about 2-3 mins after start (every couple weeks or so), then takes a couple of key offs, then back ons to restart. But it does restart and then runs fine for a time.... 2 weeks ago I was rollin' down the road and hit a pothole, and whammo, she died, and wouldn't restart. I thought, "great it was the intertia cut-off going bad." I had it towed to the shop where they did some diagnosis and told me it threw a PO231 code.
The tech then said he was doing the diagnostic manual directed test, and swapped out the fuel pump relay, and it started right up. New relay, out the door. A few days later on the way to work about 2 - 3 minutes after start, she dies again. I hang my head, say a curse word, and key it a couple times, and it starts back up and runs fine. Presently speaking she's back at the shop, but the owner, who's a straight up dude was loath to take her back, because it was running fine at the time.... I've got to figure this thing out before I drive it off a cliff.
Truck -- 2001 7700 XLT 5.4L 88K miles
Symptoms -- Random interval engine stops with short delay to restart, 1 hard bump engine stop with no restart. PO231 code (after the hard bump no restart). Didn't check it previously (wasn't aware there were "soft" codes).
Troubleshooting to date -- 1 new fuel pump, 1 new fuel pump relay.
Only things left are the inertia cut-off switch (which apparently don't go bad that often), and the wiring itself/connections to the different components....

I have a 1995 ford ranger v6 4.0 and for this week Ive been having a problem, stalling... It only happens when I do quick "stop and go" driving. Even sometimes at stop lights it wants to stall, the only way to keep it going is to keep my foot on the gas.
Now for a while when its cold or my truck has been sitting for a day or two the truck doesn't start on the first click.
I've had the fuel pressure checked, changed fuel pump, and starter. I have no check engine light on at the moment. Tomorrow I am gonna check with my scan tool just to make sure. But, it could be fuel pressure regulator, idle air control actuator, egr valve? How I should go along doing this?

It's been a long time since I have posted here mainly because my truck was wearing a bow tie for awhile. But my wife was nice enough to tell me the Bow Tie wearing truck was making a funny noise on New Years Day (seems a small drum corps took up residence in the oil pan). So anyhow now I am back in a real truck . My new to me 1998 F150 5.4 Liter ran fine until yesterday. It started idling rough and almost stalling at red lights. about halfway home the CEL light came on and is throwing a P0171 code.
So far I have checked for vacuum leaks including all the elbows on the PCV system' tried the spray test with a can of flammable break fluid and a can of starting fluid (man I love the smell of that stuff) could not find a leak. Cleaned the MAF sensor and the K&N air filter (not a fan of these) IAC seems to be working. Only thing I know that is leaking for sure is the driver side exhaust after the cat. But that is the wrong bank if I am correct on which bank is which.
So why only one bank running lean and why does it act like it is only firing on 4 cylinders?

2 questions regarding our 2001 F150 Supercrew. My 2 questions are:
My 2001 Ford F150 Supercrew (5.4L, 230,000 miles)has the check engine light on with the code reader telling me that it is the P0174. The truck would run rough when cold (usually in the mornings) and sometimes it would get close to stalling out when coming to a stop light. So we would quickly put it in park and give it some gas to rev it up a bit. After the truck gets warmed up, it runs great with no hint of the rough idle. Since this all started I have changed out the PCV valve and replaced the PCV hose (including the elbow). I have also replaced the Idle Air Control unit but that didn't really make a difference.
We then experienced a cylinder #4 misfire which we resolved by changing out the cop with a new Motorcraft unit. The misfire went away but we still had the problem of running rough at idle to the point of stalling out at stops when the engine is cold. A few weeks ago we cleaned the MAF sensor and that seemed to work. The truck doesn't run as rough now (when cold) at stop-lights, but occasionally it will still have the loping idle. We cleared the check engine code and it stayed off for about a week before returning.
I don't know what else to check other than trying to see if there is some type of vacuum leak, but I don't have access to a smoke machine nor would I know how or where to hook one up. Removing and cleaning the throttle body would work? What could be causing the trouble, or what I should do to further isolate or troubleshoot the problem? I saw a you-tube video on the F150 intake manifold gasket possibly being the problem and although I hope that isn't the trouble with my truck, if it is then I will have to deal with it. We need the truck to get to work and the car is now due for a registration renewal, but we can't get a California smog certificate with the check engine light on.

I'm trying to diagnose an issue my sister has been having on her 2010 with the V6. Dealer can't find anything wrong with it
She says when she stops to get gas, it has trouble starting back. Will crank, but not start. has to try it several times. Sometimes pumping gas will work. (Sounds maybe like IAC to me)
She says when she's driving, that sometimes it will quit. Best I can understand from her description, it's when she's off the throttle. She says most of the time it will start right back up then.
She also says sometimes when she's trying to crank it back, it acts almost like a bad starter, or battery. Starter getting slower, then speeding back up. Also says that sometimes it acts like it's low on power. She has to floor it to make it go.
My thoughts are IAC or faulty fuel pump?

Bought this truck a few months back. Nothing but problems. I always thought it has felt a little underpowered and hesitant. I chalked it up to being a 5.4l in a f250. Well now im thinking it has been a symptom all along.
Lately, the truck has been stalling at stops. Randomly, but not often. The truck idles at 750rpm when I start it, but after driving and then coming to a stop while in overdrive it idles at 400rpm. This seems too low to me.
It hesitates occasionally when giving it throttle. Just today it got really bad and was almost unresponsive. I would hit the throttle and it would just idle while randomly kind of shooting up in RPS and shuddering. It finally produced some error codes, it looks like, but I am afraid to drive it all the way to the autozone.
I am thinking TPS. Is the TPS attached to the pedal or is the TPS attached to throttle body under the hood? I've read some conflicting stuff about this. The good news is that if it is the TPS then it should act like a whole new truck after I replace it.

So my car just started randomly dying everytime i came to a stop. Just shudders and off and then when i go to restart it cranks no problem but will not start. If i just wait for about 5 minutes it will start right up again but then die on the next few stops. A few hours later i go try again and i get it home no problem but still kept the rpms up when i wasnt moving. Filled up with 93 and put some gas treatment and it seems to be fine. What can it be? just bad gas or water in it? or could it be battery, alternator or clutch?

I have a 2000 Saab 9-3, the 'Viggen' model, and it almost always runs just fine. But once in a while, maybe every couple of thousand miles, the engine just stops, in the middle of cruising along. The power steering goes dead immediately. So far, it has only happened in city driving, not going fast or accelerating hard. I can restart immediately by just depressing the clutch and running the starter. From other reading, I wonder whether it's the Direct Ignition Casset? The engine is the 2.3 L turbo.

My brakes are working fine, and the car starts up okay. However, when I press on the gas and go anywhere over 20 mph or so, my car will start, then stop, then start, then stop... Until I step off the gas. There's also a semi-frequent squealing noise whenever I press the gas. The Service Engine Soon Light is on. What it is?
